Title: Resist coating method
Inventor: ASHIKAGA YUJI
IPC: G03F7/16
Filed: 1986-02-18
Abstract: PURPOSE:To improve the yield of a coating method for a resist by dropping the resist on the surface of a wafer, then rotating the wafer at first rotating speed, then decelerating the speed, and then rotating the wafer at the second speed higher than the first speed to uniformly coat the entire surface of the wafer with the resist without irregularity. CONSTITUTION:A wafer is rotated at a first rotating speed N1 while dropping a predetermined quantity of a predetermined photoresist by a nozzle to approximately the center of the surface of a wafer after pretreating (cleaning) in a first step A, and the speed is gradually decelerated. The resist may not necessarily be dropped over the entire time, but be dropped before starting the rotation. Since the resist coated on the entire wafer is radially irregular and large in its thickness, the wafer is rotated at a second rotating speed N2 higher than the first speed N1 for a predetermined time. Thus, the thickness of the resist coating film is uniform in a necessary predetermined thickness over the entire surface of the wafer.

Abstract: PURPOSE:To smoothly perform the starting and stopping of the conveying in and out of the press works by reciprocating a gear by way of a crank mechanism, transmitting its movement to a pair of arms to oscillate a shaft thereby moving the carriage. CONSTITUTION:A crank mechanism 15 is rotated by a motor 17 and when a gear 9 is reciprocatively turned by a sector gear 12, this movement is transmitted to a gear 10 by way of an intermediate gear 11. The turning of the gear 10 is transmitted to an arm 1 by way of a shaft 8 and the arm 1 oscillates about the shaft 8. Along with this, the 2nd arm 2 oscillates about a pivotal axis 7 and the shaft 8 moves up and down by tracing an arc form locus. Hence, the arm 2 plays the role of a guide for the shaft 8. In the half cycle of this oscillation, the carriage 3 mounted to the pin 4 at the bottonm end of the arm 1 makes linear motion. As a result of this, the carriage 3 moves without accompanying shock and its stop position becomes accurate.

Title: Dropout detector
Inventor: NISHI KIYOMOTO
IPC: H04N5/94
Filed: 1983-03-02
Abstract: PURPOSE:To detect a dropout faithfully and securely by extracting dropout components with a high frequency component which generates in a sound signal and detecting a component whose level is higher than an optional signal level as the dropout. CONSTITUTION:A sound FM signal having a dropout is demodulated by an FM demodulator 1, its band is limited by a low-pass filter 2, and the sound signal passed through a de-emphasis circuit 3 has abnormality as shown waveforms (a) and (b). This sound signal is passed through an LPF7 to have sharp impulsive waveform disorder as shown by waveforms a' and b' and frequency components of the parts a' and b' have relative high frequencies, so an HPF8 is used to extract only pulse components generated due to a dropout. Thus, only a'' and b'' having the high frequency components are extracted and inputted to a level detector 9. This level detector 9 is set to optional voltages V2 and V3 and generates a pulse D when the voltage of a waveform C is higher than V2 or lower than V3. This output pulse D is a dropout detection signal, which serves as the control signal of a dropout compensating circuit 4 to compensate the dropout.

Filed: 1990-02-16
Abstract: PURPOSE:To preclude toner scattering and toner fogging and to improve print quality by providing an agitator, which is formed of conductive magnets and applies a bias voltage, internally and agitating toner. CONSTITUTION:In this developing unit 10, power is transmitted to the gear 4 of the agitator 15 by a gear train extending from an image carrier drum 5 through a magnet roll 11, so that the conductive magnets 1 and 2 rotate. Magnetic powder stagnated at a lower part because of specific gravity is attracted by the rotating magnets 1 and 2 and further applied with a bias voltage from outside, so the magnetic powder which is attracted by the magnets 1 and 2 is prevented from scattering and excited to agitate the toner sufficiently. Consequently, the toner can be charged electrostatically and sufficiently to preclude toner scattering and toner fogging on a print, thereby securing the sharp print quality.

Abstract: PURPOSE:To improve the S/N ratio of a reproduced signal by laminating the 1st and the 2nd magnetic film layer which differ in refractive index on a transparent substrate and utilizing Fraday effect and Kerr effect in combination. CONSTITUTION:On the transparent substrate 5, the 1st magnetic layer 1 and the 2nd magnetic layer 2 are laminated. Both magnetic layers consists of vertically magnetized films which differ in refractive index sufficiently and reproducing light is reflected by the interface between the magnetic layers 1 and 2. The repoducing light A entered from the substrate side 5 is reflected partially by the surface of the 1st magnetic layer 1 and its reflected light B has the plane of polarization rotated by Kerr effect. The transmitted light has the plane of polarization rotated by Faraday effect, and also has the plane of polarization rotated by Kerr effect when reflected by the interface with the magnetic film 2 and the plane of the polarization rotated again by Faraday effect when transmitted through the magnetic film 1 to obtain reflected light C. The directions of rotations bt Faraday effect and Kerr effect are made coincide with each other. Consequently, the reflected light B and reflected light C become to be arithmetically, thereby improving the S/N ratio of reproduction.
